LIFT FOR GIN BREASTS.

Application filed February 9, 1825. Serial No. 8,084.

To all whom it may concern:

Be it known that I, FREDERICK B. CUMB- s'roN, a citizen of the United States, residing at Blooming Grove, in the county of Navarro, State of Texas, have invented certain new and useful Improvements in Lifts for Gin Breasts, of which the following is a specification.

This invent-ion relates to an improvement in lifts for gin breasts and has for its object the provision of a device of this character which may be readily operated either by hand or by foot and which may be readily held or locked in position although easily released.

A further object is the provision of a device of this character which is of simple and durable construction, which is reliable in operation, which is easily controlled, and which is comparatively inexpensive to 'manufacture and install.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being bad to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a view showing an embodiment of the invention applied to a gin, and

Figure 2 is a perspective view of parts of the invention detached from the gin.

Referring to the drawings, the numeral 1 designates a gin which may be of any desired construction and which has a gin breast 2 hinged or mounted for movement for lifting in a conventional manner.

The lift which constitutes the present invention includes a shaft 3 journaled in suitable bearings provided therefor on the frame of the gin. One end of the shaft projects beyond the frame and has a squared portion 4. A foot lever, designated generally at 5, is provided and has a bearing portion 6 engaged with the squared portion l of the shaft 3, so that the lever 5 is fixed on the shaft 3. The lever 5 has a forwardly extending arm 7 formed with a foot piece 8 and also has a rearwardly extending arm 9 terminating in a bifurcated or yoked end 10 which is pivotally connected by a pin 11 with the lower end of a combined hand lever and lock rod, designated generally at 12. The combined hand lever and lock rod 12 operates through a strap 13 secured to the frame of the gin and has a tooth 14 engageable with the strap 13 to hold the gin breast elevated. On the upper end of the combined hand lever and lock rod 12 a hand grip 15 is provided.

Motion transmission means is provided between the shaft- 3 and the gin breast and preferably comprises a crank arm 16 having one end fixed to the shaft 3 and having its other end pivotally connected, as at 17, to a rod or link 18. The rod or link 18 is in turn pivotally connected, as at 19, to a bracket 20 secured to the gin breast.

With this arrangement when the foot piece 8 of the foot lever 5 is engaged by the foot and depressed, the shaft 3 is rotated to swing the crank arm 16 in a counter-clockwise direction as viewed in Figure 2. This movement of the crank arm 16 operates through the link 18 in the bracket 20 to elevate or lift the gin breast. The movement imparted to the foot lever 5 to elevate the gin breast simultaneously moves the hand lever 12 upwardly and when the gin breast has been completely elevated the tooth 14 is engaged with the strap 13. Of course, more than one tooth lei may be provided if it is desired to hold the gin breast in any intermediate position between that of full elevation and its ordinary position. To release the gin breast, the hand grip 15 is grasped and the hand lever and lock rod 12 is pulled upwardly and then swung in a clockwise direction as viewed in Figures 1 and 2 so as to move the tooth 1 1 out of the path of the portion of the strap 13 which it engages, whereupon the combined hand lever and lock rod is moved downwardly to permit the gin breast to move back to normal position. Of course, the combined hand lever and lock rod may be also used to elevate the gin breast if this is found desirable.

I claim:

1. In a lift for gin breasts, a rock shaft, motion transmission means between the shaft and the gin breast, a foot lever fixed on said shaft having a. forwardly extend ing arm designed to be engaged by the foot of the operator and also having a rearwardly extending arm, and a combined hand and lock lever connected to said rearwardly extending arm.

2. In a lift for gin breasts, a rock shaft, motion transmission means between the rock shaft and the gin breast, a foot lever fixed on said shaft and having an arm designed to be engaged by the foot of the operator, a second arm extending on the opposite side of the shaft, and a lever connected to said second arm and having a tooth adapted for engagement with a part carried in the gin to lock the breast elevated.

3. In a lift for gin breasts, a rock shaft, motion transmission means between the. rock shaft and the gin breast, a foot lever fixed on said shaft and having an arm designed to be engaged by the foot of the operator, a second arm extending on the opposite side of the shaft, and a lever connected to said second arm and having a hand grip and a tooth adapted for engagement With a part carried in the gin to lock the breast elevated.

FREDERICK B. CUMPSTON.
